Three forces shaping the week
AI spending under the microscope
Meta’s revenue rose 26%, but $34.9 billion of quarterly capex pushed free cash flow negative and the stock fell about 7% Thursday.
Oil keeps climbing
Brent settled at $116.72, up about 6% for the week and its highest since April, as Middle East supply worries grew.
Leadership broadens
The S&P 500 and Nasdaq slipped, but the Russell 2000 rose 2% and the Dow logged a third straight weekly gain.
